Return to Castle Wolfenstein, Id Software's long-awaited reboot of the Wolfenstein series, bowed in November 2001. It had a good singleplayer mode (before the term "campaign" took hold) but was well known for its multiplayer, which spawned the free Enemy Territory game. We're going to go on through a complete playthrough of the single player mode, complete with Nazis, the occult, and atomic supermen! RTCW kicked off the glut of World War 2 shooters, with Medal of Honor: Allied Assault and Call of Duty following on its heels. Where Wolfenstein differs is that it has always had a science fiction bent. The occult, supermachines, high technology and more play large factors in the plots, often based on crazed Nazi schemes.
